Aqueous nano hollow glass bead heat-preservation thermal-insulating coating and preparation method thereof

Abstract

The invention discloses an aqueous nano hollow glass bead heat-preservation thermal-insulating coating and a preparation method thereof. The aqueous nano hollow glass bead heat-preservation thermal-insulating coating consists of the following components in parts by weight: 10.5-20 parts of deionized water, 0.8-1 part of hydroxyethyl cellulose, 40-45 parts of a pure acrylic emulsion, 0.6-0.8 part of a 5040 sodium salt dispersant, 0.2-0.3 part of a wetting agent, 15-20 parts of nano titanium dioxide, 5-10 parts of a calcium carbonate pigment filler, 0.15-0.2 part of an AMP-95 multifunctional aid, 5-8 parts of a texanol film formation aid, 1.5-2 parts of an ethylene glycol anti-freezing agent, 0.2-0.3 part of a fungicide, 0.2-0.3 part of an anti-mold agent, 0.2-0.4 part of a 681F defoaming agent, 0.5-1.2 parts of a thickening agent and 20-25 parts of hollow glass beads. The aqueous nano hollow glass bead heat-preservation thermal-insulating coating disclosed by the invention has the advantages of being short in surface drying time, excellent in anti-aging property, low in heat conduction coefficient, good in heat-preservation thermal-insulating property, excellent in tension resistance, and the like.

Description

technical field

[0001] The invention relates to the technical field of thermal insulation coatings for buildings, in particular to a water-based nano hollow glass bead thermal insulation coating and a preparation method thereof. Background technique

[0002] Building heating and air conditioning consume a lot of energy during building use. According to reports, my country's building energy consumption has accounted for 30% of the total energy consumption of the whole society, and building energy conservation is imminent. The most direct and effective way to save energy in buildings is to use thermal insulation materials to combine with buildings, so that the buildings can achieve thermal insulation and heat insulation, so as to reduce the use of heating and air conditioning, so as to achieve the purpose of energy saving.

[0003] At present, building thermal insulation is mainly covered with panels such as polystyrene particles and rock wool boards on the roof or walls of bu...
